How does autoclave indicator tape change color?

The indicator ink on the tape changes from yellow to black after exposure to steam sterilization conditions of 121°C for 20 minutes or 134°C for 4 minutes. The color change indicates exposure to the sterilization process.

Can autoclave indicator tape be used for EO sterilization?

No. This tape is designed for steam sterilization only. EO sterilization requires an appropriate EO-compatible indicator product. Using the wrong type of indicator may lead to incorrect interpretation.

What width of autoclave tape should I choose?

1/2" width is suitable for compact packages, while 3/4" and 1" widths are commonly used for larger packages and CSR wraps.

Does color-changing autoclave tape mean the instrument is sterile?

No. The color change indicates that the outside of the pack was exposed to the steam sterilization process. It does not confirm that steam reached the inside of the pack or that the contents are sterile. Use an internal indicator together with external indicator tape for more complete monitoring.

Why is my autoclave indicator tape not sticking?

Make sure the application surface is clean and dry before applying the tape.

Why does autoclave indicator tape leave adhesive residue?

Under normal use conditions, the tape should not easily leave adhesive residue. If residue occurs, check the sterilization parameters, the condition of the application surface, and the product expiration date.

Why did my autoclave indicator tape not change color?

Confirm that the sterilization cycle reached the required conditions: 121°C for 20 minutes or 134°C for 4 minutes. Common causes include insufficient temperature or exposure time, packs stacked too tightly, or poor steam contact. Do not release the load as sterilized if the tape does not change color.
